How do I create my own collision field for the smoke solver?

Hi everyone,

I am trying to set the values to a collision field in a gas wrangle. I am using the gas build collision mask node to create the necessary fields and then I am trying to set values with a gas wrangle.

Is it even possible to do it this way? 

I have a example scene that shows how I set it up now, that doesn't work.

My purpose for this that I want to be able to simulate a 2d smoke simulation and collide to an object on a different height for every voxel.

I will eventually want a separate height field that will accumulate the density and this heightfield will be the Y position for the voxel to check the collision.

I am quite new to smoke/pyro simulations, so this scene probably doesn't make any sense :)
